Abstract

a presente invenção refere-se a uma sonda de imersão para determinar mudanças de fase por análise térmica de uma amostra de um metal fundido. a sonda de imersão compreende uma cabeça de medição incluindo uma primeira extremidade que é uma extremidade de imersão e uma segunda extremidade oposta tendo uma face terminal, e uma câmara de amostra disposta dentro da cabeça de medição. uma abertura em comunicação com a câmara de amostra é formada na face terminal da segunda extremidade da cabeça de medição. a abertura está livre de quaisquer restrições. a câmara de amostra inclui um primeiro termopar tendo uma primeira junção de termopar encerrada dentro de uma parede. a parede tem uma geometria interna uniforme. uma relação d/h e um diâmetro interno d da câmara de amostra com um comprimento h se estendendo entre a abertura e a primeira junção de termopar está entre 0,1 e 1,2.The present invention relates to an immersion probe for determining phase changes by thermal analysis of a molten metal sample. the immersion probe comprises a measuring head including a first end which is an immersion end and an opposite second end having a terminal face, and a sample chamber disposed within the measuring head. an aperture in communication with the sample chamber is formed on the end face of the second end of the measuring head. The opening is free of any restrictions. The sample chamber includes a first thermocouple having a first thermocouple junction enclosed within a wall. The wall has a uniform internal geometry. a ratio d / h and an inner diameter d of the sample chamber with a length h extending between the opening and the first thermocouple junction is between 0.1 and 1.2.
